Settings

UART Output

9600 Baud, 8 bits, no parity bit, 1 stop bit

Configured to transmit both NMEA and UBX protocols, but no UBX messages and only the

following NMEA have been activated at start-up:

GGA, GLL, GSA, GSV, RMC, VTG, TXT

UART Input

9600 Baud, 8 bits, no parity bit, 1 stop bit, Autobauding disabled

Automatically accepts following protocols without need of explicit configuration:

UBX, NMEA, RTCM

The GPS receiver supports interleaved UBX and NMEA messages.

DDC

Fully compatible with the I2C industry standard, available for communication with an external host

CPU or u-blox cellular modules, operated in slave mode only.

NMEA and UBX are enabled as input messages, only NMEA as output messages

Maximum bit rate 400 kb/s.

TIMEPULSE

(1 Hz Nav)

1 pulse per second, synchronized at rising edge, pulse length 100 ms
